FWIW, I don't understand the last paragraph. What do
you mean by "delete a file in a buffer"? Do you mean
somehow delete a file (from disk) from a buffer that
is visiting it? Or delete it from a Dired buffer?
I'm guessing it's the latter, but in that case Dired
does do that, doesn't it?
For the rest, here's something to maybe consider:
`find-dired' gives you a snapshot of what's on disk
at a given time. Dired does that too, but for Dired
there's an optional behavior of having its display
auto-revert, to pick up any disk changes when you
revisit the Dired buffer.
Is that what you're requesting for `find-dired' too?
If so, should it be turned on by the same option,
`dired-auto-revert-buffer'? I can think that someone
might well want a different option for it.
I can also think that someone might sometimes want
the current behavior, i.e., s?he would turn off such
a new option.
For example, you might want to have a buffer with
such a `find-dired' snapshot, as reference/comparison,
as you go through and delete or modify some of the
listed files, i.e., to keep track of what you've done
so far. (But I guess such tracking would kind of be
available anyway, if you sort the `find-dired' output
by time.)
